Any way to add menthol to aqueous solution (like a toner)?

Could you use an emulsifier, solubilizer, cosolvent? I don't really understand the difference between them.


  • Emulsifier makes an emulsion ~ lotion, cream. 
    Solubilizer - alloys you to solubilize a low input of oil in water based product  and keep it clear ~ essential oil in a toner
    Cosolvent (solvent) - dissolves an ingredient ~ niacinamide in water.

    If you want to do a toner, you will need a solubilizer (water is a solvent). 

    Easy enough to google it. 
  • just mix your menthol to alcohol first then put into you toner
